Re: to delete a file
Hi,
Usually, one uses the following command (from the shell prompt)
"rm /path/to/file/filename"
To supress the confirmation message, use:
"rm -f /path/to/file/filename"
To delete recursively (i.e. a directory), and make it verbose to the screen:
rm -rfv /path/to/directory
Does that help.
Of course, from a perl script, you can either use:
system("/bin/rm -f /path/to/filename");
or
`rm -f filename`
I hope that helps,
Regards,

Re: Learning Perl chpt.13 problem
Hi, s/#.*/## The above is used either to indicate a substitution of a string. The "s" indicates substitute. The rule is, that whatever you specifiy after the "s", is the regex that you are looking for (this in the above case "#.*"). This is then separated by a "/". Anything after is the replace parameter, ended by a "/". There are other switches that can be placed after the last "/", usually: g (indicates a global search/replace) d (delete the line) HTH, Thomas Adam Please note that the content of this message is confidential between the original sender and the intended recipient(s) of the message.

Re: STDERR Question
Hi,
I think this is possible
while (<>) {
open(STDERR > /file)
close(STDERR)
}
I think thats right (I'm rather new to perl).
HTH,
Thomas Adam

Re: Telnet
Hi, Telnet, gives you the ability to access a remote machine across a network, however, I would advise against using telnet. Instead, I recommend using SSH (Secure SHell), which is much more secure.

Re: CGI-BIN

Help with cgi-script
Dear List, I am trying to write a cgi-script that adds a new user to my linux box via a web based form. The trouble is, is how do I pass variables to the program "passwd"?? This is so that when the password is sent via the form, it erncrypts the password, and adds the user??? Has anyone got any ideas? Or has a similar cgi-script I could use?? I am using the shadow password suite, if that helps.

Help needed with perl script......
Dear List, I have attached a copy of my perl script that I am writing. I am finding that I am having trouble with it. I am sure that there is a simple solution.. To cut a long story short, I have written a bash script, which uses sed and awk to convert the logfile that is generated by the Unix squid caching program. What this script does, is to convert the unix timestamp, and print various columns (which in their raw format are separated by a space), as a CSV file (comma delimited file). Thus, the final product, should be that the output field separater is a comma. I have included my perl script thus far. The problem that I am having is that once it has converted the timestamp (which it does), it then splits the rest of the file into comma separated fields, but rather than put them into the designated file, echos them to the screen. Why is this??? I have tried in vein to fix it, but I must be over-looking something. Thanking you in anticipation, Regards, Thomas Adam Linux Co-ordinator at The Purbeck School (Network Support) e-mail: [EMAIL PROTECTED] website: www.squidproxyapps.org.uk squidlog.perl

Dear List, I would just like to say thank you to all the people who help me with getting perl to open to and read a file.

I am a real begginer to perl......
Dear All, I wonder if someone could help me. I have been programming in bash for years now, but I have decided that I would like to use perl.
